Answer 1

The box in the corner shows that this is a 90 degree angle so take 42 and subtract it from 90 in order to find out what the rest of the angle is which is 48 degrees

Answer 2

This graph displays a complementary angle, meaning all sides add to a sum of 90°. Given that one side equals 42°, we can subtract 90 - 42 to find that the measure of the missing angle is 48°.
